- Carbon, Hydrogen and Oxygen are considered as framework elements. They constitute an essential part of Carbohydrates, Proteins and Fats, the basic macromolecules of all living systems.
- Light reaction takes place in the grana and dark reaction takes place in the Stroma of chloroplast. Synthesis of ATP in the chloroplast utilizing light energy is called Photophosphorylation.
- Glycolysis is a common pathway for aerobic and anaerobic organisms. It involves breakdown of respiratory substrate into pyruvic acid.
- The cytokinins are plant hormones which act primarily on cell division. It was first isolated by Miller and his coworkers in USA.
- The growth in length of plants can be measured by an instrument called Lever or Arc Auxanometer.
- Chloroplasts function as sites of photosynthetic activity.
- Auxins were discovered by Went.
- Auxins are responsible for apical dominance.
- Gibberellin causes bolting in plants.
- Ethylene is a fruit ripening hormone.
- Mitochondria is the seat of cellular respiration.
- Glycolysis is also called as EMP pathway.
- Energy is stored in the form of ATP in cells.
- Formation of ATP during electron trasnsport chain is called oxidative phosphorylation.
- Splitting of water molecules during light reaction is called photolysis.
- Dark reaction was discovered by Melvin Calvin.
- Stomatal Transpiration accounts for maximum loss of water from the plant.
- The adaptation in Opuntia to reduce transpiration is called phyllociade.
- Chemical substances used to reduce transpiration are called antitranspirants.
